I asked my cc company (Amex) and VW Credit if I could pay with a credit card. Both said "no." Was hoping to rake up those extra points since the car payment is something I have to pay. I pay my balance + car payment every month so it would be nice to have them combined.
Do your credit cards have credit access paper checks?
If so and if you have credit discipline (not a shopaholic), deposit one of those credit checks with 1-12 months worth of VW payments into your checking account then auto draft a check to VW with your monthly payment.
You'll get points for the cash deposited and be able to pay VW with credit via your checking account.
The amount of months you take out in cash should be within your comfort zone of what you'd be comfortable to pay off each month. Otherwise you'll hold a balance.
